LTE-WLAN CENTRALIZED DOWNLINK SCHEDULER
First Claim
1. A method of wireless communication, comprising:
- determining, by a base station, a plurality of user equipments (UEs) for downlink data transmission on one or more of a Long-Term Evolution (LTE) link and a wireless local area network (WLAN) link in a first transmission interval;
determining data for the downlink (DL) transmission;
jointly assigning resources for transmitting the data in the first transmission interval when the UEs are served on the one or more of the LTE link and the WLAN link, including;
prioritizing portions of the data for the DL transmission on the respective LTE and WLAN links on a per-link basis;
requesting packets for the DL transmission based on the jointly assigned resources, wherein the packets are requested from an aggregating layer of the base station for the LTE link and the WLAN link; and
;
transmitting packets received from the aggregating layer to at least a subset of the UEs during the first transmission interval.

Abstract
Techniques for managing downlink transmissions from a base station to multiple UEs over aggregated LTE and WLAN links are provided. The base station may jointly assign resources for transmitting downlink data during a scheduling instance. The resource assignment may include a prioritization based on channel conditions and system throughput when the links are considered jointly. In accordance with the joint resource assignment, the base station may build packets for the downlink transmission at an aggregating layer which, for example, may be coupled to media access control (MAC) elements associated with the respective links. The base station may then transmit the packets to at least a subset of the UEs based on the joint resource assignment.
